Yes, we are in the process of updating our packaging, so you will see more and more blue boxes over time. The contents of the DLCN20 kit have not changed. When we update a kit and change its contents, we also update the catalog number and send out a notification letter. As long as there has been no change to the catalog number of a product, and you have not received a notification letter, you can be confident that our products have not changed even if the packaging has.
